@o all whom 'it may concern:

"Be it known that I, JOHN G. SNYDER, a citizen oi the United` States,residing at Altoona., in the county of Blair and Stateof Pennsylvania,have invented nertain n'ew and*v useful Improvements in Metallic'Railway-Ties, of which the following is aspecification.

The invention lrelates to improve'mehtsin metal railway ties and it hasfor` its object the 'provisionof such a devine that will not only havesuiiicient stability to withstand the wear and tear of'tradic, .butwhich will .also have'suflicient elasticity@ to givelthe rails theresilient support necessary 'to' movement of the rolling-stock. i'.

It also has foiits object .the provision oi means for' adjusting theclamps so that the railcan be easily posi tioned and secured in place.

The inventionconsists in the novel construction,

. combination and arrangement of parts, such as will'be hereinafterfully described, pointed out in .the-Jappended claims, and illustratedin the accompanying In the drawings, in which similar reference charac-yters designate' corresponding parte, Figure 1 is a per-- spective viewof a tie embodying the invention. 2 is a plan view of the casing orshell forming the tie with the rails and clamps removed. Fig. 3 is alongi tudinal sectional view of one end of the tie with the' rail andclamp in position. Fig. 4 is a cross sectional Vview showing the shelland elastic filling. 5, 7 and 9 are, respectively, plan, end, and side'views'of the clamp. Figs. 6, 8, and 10, are, respectively, plan, end,and side views f a modified form of the clamp. Fig. 1l, isan enlargeddetail perspective view showing the bolt.A

The tie is formed of a casing or shell of 'sheet steel or other suitablemetal and Vin general shape and dimen-v sions resembles the ordinarywooden tie. It has the dat upper surface or crown 1 and the roundedsides 2,' ,and it is open atboth ends .and at lthe bottom. The edges ofthe sides," as at 3, are curved inwardly and upwardly to formsemi-elliptical springs, on the rounded part of which the tie rests.These springs, together'` with the curved sides, give to the tie therequired elasticity to meet the tratlc conditions of the road. In thecasing is the elastic 11ing`4 of such a nature as to give to the tie thestability required `and also which will permit the tie to yield to takeup the shock of the pasing load. The filling is preferably comprised ofa mixture of asphalt, bitumen and liber, which latter' may be eithermineral or vegetable. The asphalt and' .bitumen give the required bodyand cohesion to the lilling andthe fiber acts as a binder to hold themass' together. The fiber also serves to render the elastic so that itcan yieldtb the movement of the tie form springs, but also serve holdthe lling within the easing. Owing to their-formation the inwardly lunder the stress oi a load. The edges not only 5 turned edges 3 cannotspread apart under.' the weight of a passing load, but will" haveatendency to move inwardly, which would be opposed by the filling.

Owing to their formation, the inwardly and upwardly turned edges 3 ofthe tie penetrate the material of the road-bed to a considerable extent;also the compara tively wide opening in the bottom of the tie ,permitsroad-bed material to enter the tie and adhere to the filling. In thisway the tie is held against movement.

The rails are heldin place on the tie by the clamps 5. Each clamp at itsinner end is shaped to fit the baseand web of the rail and to abutagainst the under side ofthe crown. Inthe outer end of the clamp is theobli-(jue slot 6 throgh which passes the bolt 7 mounted 'in the tie.When the bolt is placed in`position its head is inserted in the opening8 in the tie and its shank, v

which is flattened, as at 9, is moved into the recess 10 extendingtowards the'rail. When in this position the head of the bolt projectsbeneath` the edges of the tie andis thereby held in place. By means ofthe oblique .slot 6 theclamp can be moved from one side to the `other tomove it toward or from the rail so that a proper adjustment of the railand the tie can be secured. The

flattened 'part 9 of the bolt prevents the turning oi the latter whenthe nut is applied. The purpose of the bolt is to hold the clamp downupon the/tie.

Longitudinal movement of the-clamp 5 is prevented by the lugs 11 whichproject from the under side of the outer end of the clamp at itscorners. `These lugs are adapted to register with the slots 12 in thetie. The

slots are parallel with the longitudinal axis of the tie.

the latter is in place. Consequently the ends of the slots .approach andrecede from the rail by very shallow steps. By moving the clamp from oneside to the other a very close adjustment relative tothe railcan besecured. When the clamp is in position the lugs engaging with the slotshold the clamp against the end thrust exerted by the rail. The bolt;when it is secured, holds the clamp in place and also holds the rail'down on the tie. By loosening the bolt theclamp can be very easilymoved from one 'side to the other tosecure a vchange in the adjustment.l 'In the modificationv shown in Figs.,6, 8 a'nd los iongitudinaliyhndthen transversei'y so that thestrips of metal can be turned down to formthe lugs inside of the edges of the clamp. The clamp iti this instanceis adjusted in the saine way as in the formerinstanee. Othermodifications of the -deviee are obvious. l

Having thus described my invention what Incl-:Juin

and desire to secure by Letters Patent is:

1. A metallic railway tie comprising :l casing 0l: shell open atthebottoni with the edges of the sides turned inwardly and upwardly to formsprings, and means for securingthe ruil to said tie. l

2. A metallic railway tievcomprising; a ensingor shell open ut theBottom with the edges of the sides turned inwardly und upwardly to formsprings, an eiustie filling for the easing, und ineens for securing theralil to Athe tie'.

3. A metallic railway tie comprising;l .ft easing or shell provided with:1 plurality of slots parallel with the longi- `saisie?" tndinai axis ofthe tie and said slots arranged so that their ends meet u lineextending,l obliquely around the tie, und n mii-clamp provided withlugs' adapted' to register with said sluts. Y

4. A metalle railway tie comprising a casing; or shell 'provided with :lplurality of pnruliel siots extendim,r iong'hl tndnnlly of the tie andarranged to extend obliqnely around'the tie, :i rail-clamp having; lugsadapted to register with Said slots and `provided with n grooveextending parallel with the oblique line running through tlleends ofsalid slots, and n holt mounted in said casing und engaging with sslidgroove in thc rnil chimp,
